Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

According to the attached drawing 1, the utility model relates to a marine air supporting automatic control system, including the air supporting jar with locate the sewage pump 6 on the oil sewage import front connecting line of air supporting jar body bottom, locate the sediment connecting line position department's of air supporting jar body top row sediment mouth water level switch 1, locate the fluorescent lamp 2 at air supporting jar body top, locate the photosensitive sensor 3 on air supporting jar body upper portion, locate the opening valve 5 on the processing back water purification delivery port department connecting line of air supporting jar body bottom side wall position department. The air-floating tank is of an inner cylinder structure and an outer cylinder structure which are sleeved in a ring mode, the top of the outer cylinder is closed, the top of the inner cylinder is slightly lower than the height of the side wall of the outer cylinder, and a gap between the air-floating tank and the inner wall of the top of the outer cylinder is an inlet through which oil sewage and dissolved air water enter a cavity between the inner cylinder and the outer cylinder from the inner cylinder. The photosensitive sensor 3 for detecting the thickness of the scum layer is arranged on the outer side wall of the air floatation tank body and is provided with two positions with different heights, wherein one of the high positions is arranged at a position 50 +/-5 mm away from the top end of the outer side wall of the tank body, the other one of the low positions is arranged at a horizontal position 100 +/-5 mm away from the lower part of the top end of the inner tank body, and the height of the set position of the photosensitive sensor 3 can be properly adjusted according to the volume of the air floatation tank and the requirement of sewage treatment capacity. And a gas-dissolved water inlet branch is also arranged on a connecting pipeline between the oily water inlet at the bottom of the air floatation tank body and the sewage pump 6.

The sewage pump 6, the water level switch 1, the fluorescent lamp 2, the photosensitive sensor 3 and the opening valve 5 are respectively in circuit connection with the control cabinet 4, and are respectively powered and controlled by the control cabinet 4, so that the automatic control of the sewage treatment process is realized.

The fluorescent lamp 2 is a light source, so that whether the fluorescent lamp 2 is in a normal working state or not can be observed conveniently, the fluorescent lamp 2 is integrally fixed in the air flotation tank body, and the working state of the fluorescent lamp 2 is observed in a mode that an observation window is arranged at the top of the air flotation tank body beside the fluorescent lamp. When the fluorescent lamp 2 breaks down, the fluorescent lamp can be replaced and maintained in time.

The utility model discloses a control working process and theory of operation as follows:

after the equipment is started, the fluorescent lamp 2 is turned on, the control cabinet 4 controls the sewage pump 6 to be started, the sewage pump pumps oily water into the cavity of the inner cylinder body through the corresponding pipeline at the bottom of the air floatation tank body, the dissolved air water is synchronously pumped into the cavity of the inner cylinder body through the corresponding pipeline through the dissolved air releaser, and meanwhile, the oily water and the dissolved air water can also be introduced into the cavity between the inner cylinder body and the outer cylinder body from the top of the inner cylinder body. The water level switch 1 is used for detecting the water level in the air floatation tank body and feeding back an electric signal to the control cabinet 4, when the water level is at a high position, the water level is lowered by opening the opening valve 5 greatly, and when the water level is at a low position, the water level is raised by closing the opening valve 5 slightly. Suspended solid and oil drop in the greasy dirt aquatic combine and come-up to the surface of water with the small bubble of dissolved air aquatic, and the scum layer in the flotation tank is more and more thick, and when the light of fluorescent lamp 2 can not be responded to photosensitive sensor 3 when locating low position department, the signal of telecommunication is given switch board 4, is closed by switch board 4 control opening valve 5, makes the internal water level of flotation tank rise, and the dross that is located the surface of water top layer floats thereupon to the dross discharge port at flotation tank top to discharge through the sediment pipeline. Along with the scum discharge, the photosensitive sensor 3 at the high position senses the light of the fluorescent lamp 2, the control cabinet 4 controls the opening valve 5 to open, and the treated purified water continues to discharge water from the purified water outlet of the air floatation tank body. Because the scum discharge pipeline is positioned at the top of the tank body, and the photosensitive sensor 3 at the high position senses the light of the fluorescent lamp 2, the scum on the water surface is not completely discharged, and the discharged scum is only the scum at the highest position, the water content of the discharged scum is lower, and the cabin capacity required by scum storage is reduced. The utility model discloses whole automatic control that realizes, the treatment effeciency is high, moreover because compact structure, the volume is less, the specially adapted marine sewage treatment system.
